PART two – merchandise

2.1 ROADWAY BASE (GRANULAR BASE COURSE)

  A. General:  Sound present material, or angular crushed stone, clean and free from organic matter and unsuitable material or different injurious substances and in such condition that it will be without delay compacted beneath watering and rolling to create a firm and stable base.

  B. necessities (Perform the subsequent each a thousand conductor m):  Gradation necessities of the road base material, once tested in accordance with ASTM C136 shall be as follows:

D. Gradation of the road base material shall have Associate in Nursing “S-shaped curve” that plots higher than the utmost density line (MDL) for the and four.75 millimetre fraction and below the MDL for fine fraction. additionally, it's counseled to be outside of the “restricted zone”.  Gradation is allowed to undergo the “restricted zone” if there's a history of thriving performance or supporting take a look at results.

  A. The Contractor shall examine the subgrade elevations, grade, tolerance, dimensions, compaction and also the conditions beneath that the road base work is to be performed and proper any unsatisfying conditions instantly before putting base materials.

  B. don't proceed with the work till unsatisfying conditions are corrected in a very manner acceptable to the Owner.

3.2 PLACING OF road BASE AND SHOULDER MATERIAL

  A. Deliver road base and shoulder material as the same mixture and place on the road and shoulder bed by suggests that of controlled mechanical spreader, and at the same amount per linear meter and at a rate which is able to give given|the desired} compacted thickness specified.  Avoid segregation of fabric and material not uniform in mixture.

  B. Place material in compacted layers of roughly equal thickness. Unless otherwise approved, thickness isn't to exceed a hundred and fifty millimetre for anybody layer. once placed in two or a lot of layers, allow initial layer to dry simply sufficiently for stability throughout putting of the next layer. allow the finished base to dry simply sufficient  for stability throughout putting of any building material.

  A. Compaction:  Compact road base and shoulder, and each layer thence to not but 100% of most density in accordance with ASTM D1557, Method D. take a look at density of compacted base in accordance with ASTM D2167 or ASTM D 2922 or ASTM D1556.  Conduct one take a look at for every 2000 sq m of in-place material, however in no case but 3 tests daily for every layer.  Perform ASTM D1557 once for each ten field density tests of ASTM D1556, ASTM D 2922 or ASTM D2167.

  B. Grade Tolerance:  The surface of the finished base shall not vary by over + ten millimetre once tested with a 3-meter hand tool and once placed on, and parallel or perpendicular to the middle line of the road and also the compacted base shall not vary by over + ten millimetre from the desired elevation.  Correct all depressions and humps surpassing the required tolerances.
