It shall consist of any combination of gravel, sand, silt and clay or other approved combination of materials free from vegetable or other objectionable matter.
It may be materials encountered in the construction site or materials obtained from approved sources. The crushed or uncrushed granular material shall consist of hard, durable stones and rocks, of accepted quality, free from an excess of flat, elongated, soft or disintegrated pieces or other objectionable matter. It is the intent of this Specification to utilize soils existing on the roadbed if the quality is satisfactory. The soil-aggregate shall conform to the grading requirements of Table The materials passing the 4.
The plasticity index shall not be less than 4 nor more than It shall conform to the applicable requirements of Subsection Where soil-aggregate required is already in place, the Contractor shall not be responsible for its grading or quality except for removal of oversized materials as directed by the Engineer. In general, salvaged soil-aggregate to be used for lime stabilized road mix base course will consist of material meeting the requirements given in Subsection The amount of lime to be added to the soil-aggregate shall be from 3 to 12 mass percent of the dry soil.
The exact percentage to be added shall be fixed by the Engineer on the basis of preliminary laboratory tests and trial mixes of materials furnished. Lime shall not be applied during windy, rainy or impending bad weather. In the event rain occurs during the operations, work shall be promptly stopped and the entire section shall be reconstructed in accordance with this Specification. The equipment to be used by the Contractor shall include scarifying, pulverizing, mixing, spreading, hauling, watering, finishing and compacting equipment and a slurry lime distributor.
It shall be equipped with a power unit for the pump and full circulation spray bars adjustable laterally and vertically, as well as agitator to prevent setting of lime solids. These equipment shall be on the project site in good condition and shall have been approved by the Engineer, both as to type and condition, and provided with experienced operators before the start of construction. When new soil-aggregate is to be used, the existing roadbed shall be scarified lightly and bladed to uniform grade and to the cross- section shown on the Plans and shall then be rolled or watered and rolled, as directed.
If so ordered by the Engineer, depressions shall first be filled and weak portions of the roadbed strengthened with new soil-aggregate. At least one day shall then be allowed for measuring, sampling and testing for approval of quantity and gradation before the windrow is spread for application of hydrated lime. If the surface moisture of the soil-aggregate is more than 2 mass percent of the dry aggregate, the soil aggregate shall be turned by blades or disc harrows or otherwise aerated until the moisture content is reduced to 2 percent or less.
The soil-aggregate shall then be spread smoothly and uniformly over half the road or other convenient width of the surface ready for the application of hydrated lime. When material in the existing roadbed is to be used for mixing, the surface shall be scarified lightly and bladed to uniform grade and to the cross-section shown on the Plans. The reshaped surface shall then be scarified again to the depth ordered by the Engineer and in such manner as to leave a foundation of undisturbed material parallel, both in profile and cross-section, the proposed finished surface.
The loosened materials shall be bladed aside into a windrow at the side of the road, and the undisturbed material roiled, or watered and rolled, as directed. The hydrated lime shall be uniformly spread at specified percent using either the dry or slurry wet methods. It shall be distributed in successive applications, in such amount and at such intervals as directed.
The mixing equipment shall follow immediately behind the distributor, after each application to partially mix the lime with the soil-aggregate. Dry lime should not be spread under windy conditions to avoid excessive dustings. It shall be applied only to such areas as can be mixed into the soil-. Dry application encompass either spotting bags of lime in equal predetermined transverse and longitudinal intervals or applying bulk lime from suitably equipped self-unloading trucks.
An approved spreader is preferable for uniform distribution. If lime slurry is employed, the preparation facilities should be approved by the Engineer. A typical slurry ratio is 1 tonne lime to 2 cubic metre water.
The actual mixing proportion depends upon the percent of lime, specified type of soil and its moisture condition. The slurry is distributed by one or more passes over a measured area until the specified percentage based on lime solids content is obtained.
To prevent run-off and consequent non-uniformity of lime distribution, the slurry is mixed in immediately after each spreading pass.
After the last lime application and partial mixing, the entire mass of the mixture shall be windrowed on the road surface and then mixed by blading the mixture from side to side of the road, or by manipulation producing equivalent results, until the whole mass has a uniform color and the mixture is free from fat or lean spots or balls of unmixed particles.
During the mixing operations, care shall be taken to avoid cutting into the underlying course. When directed, the mixing process shall be confined to part of the width or area of the road so as to allow traffic to pass. Should the mixture show an excess, deficiency or uneven distribution of lime, the condition shall be corrected by the addition of soil-aggregate or lime as required and then remix. If the mixture contains excessive amounts of moisture or volatile matter, as may be encountered in slurry application method, it shall be bladed, aerated or otherwise manipulated until the moisture and volatile content are satisfactory.
The spreading of the mix shall not be done when the surface to be covered is in an unsatisfactory condition. When the mixing operations have been satisfactorily completed, the mixture shall be formed into a windrow of uniform cross-section. The material shall be spread by a self-propelled pneumatic-tire blade grader or a mechanical spreader of approved type. In spreading from the windrow, care shall be taken to avoid cutting into the underlying course.
After the material is spread, the surface shall be rolled.
Rolling shall be parallel to the road center line and shall commence at the outer edges of the road, overlapping the shoulders and progress toward the center, overlapping on successive passes by at least one-half the width of the roller, except that on superelevated curves rolling shall progress from the lower to the upper edge. During compaction, the surface shall be dragged or bladed as necessary to fill ruts and to remove incipient corrugation or other irregularities.
Rolling shall continue until the surface is of uniform texture and satisfactory compaction is obtained. Initial rolling shall be performed with a pneumatic tire roller and final rolling with a 3-wheel or tandem-type steel wheel roller. Rolling shall be discontinued whenever it begins to produce excessive pulverizing of the aggregate or displacement of the mixture.
When the compacted thickness of the road mix lime stabilized base course is to be more than mm, the mixture shall be spread from the windrow and compacted in two 2 approximately equal layers, the first layer to be bladed and rolled before the second layer is spread.

Actually, the name of brand of additives is not stated in the blue bcoz blue book is a standard guideline. Not a product brochure. Still, additives are based in phil. Climate, soil strata,environment, etch. Hi po! GOOD day, badly needed din po ako. I and my dad para sa projects niya and copy paste na lang sana.
Para maturuan ko din siya in an easier way, ehehehe, plsss and thank you po pa-send sa allynestimo gmail. Godbless you.. Since Philippines did not try to update project specification adapting latest innovative technology specially concrete and steel and even test procedures. In this forum, mostly know only about the blue book volume II. Eventually blue book comprise into three volumes, volume I — about contracts, vol II roads, bridges, ports and highways, vol. III for buildings and I think includes water works.
I have seen volume III issued in some municipalities. And there were many updates about all this volumes. Quality in materials and craftsmanship are very essential considering we are exposed to severe and dangerous zone earthquakes, extreme weather exposure etc.
The department heads of the DPWH must be serious about the quality,. Maybe only the blue is familiar, but before the blue there is the so called red book. I have work in one of the iconic project here in KSA which is the King Abdulazis Aiport Project, but the approached in technicality is very great, not just by sticking in the specifications.
One thing that is nice is you can see how people have reviewed the roof gutters that they have and be able to avoid some of the pit falls that can happen with cheep or poorly made roof gutters. Vuba Supplies is a top notch service provider for all your flooring necessities including a range of garage floor paints, anti slip paints, wood floor paints, roof tile paint , self levelling compound , garage floor tiles and so on. Any harm requirements to be used care of correct away and not left.
Ano po ba ang advantage pag accredited materials engineer? There is a big advantages for taking accreditation for Materials Engineer. Materials Engineers for Civil Work is a part of civil engineering discipline that are conversant regarding Materials Testing, Interpreting test results, its application and moreover understanding materials behavior. To become accredited ME is very useful.
Obviously ME-II should be highly qualified and shall be competent. To highlight something in my point of view and observations for which i think this msg. Passing the exam for ME-II without any acceptable experience may not warrant as a competent materials engineer.
Here in abroad, the research and application for specification are intensive, updated, enhanced and modified. There are committee assigned for specification development and enhancement. Generally to become competent materials engineer are most likely requires extensive experience and involvement in big projects and doing the right practice but some ME-II proud to have several years of experience but still doing malpractice.
Distributing rightful technical information to all accredited ME for free and use the internet technology as tool for improvement.
