Methodology of Aggregate Base

1.SCOPE

This method statement described various activities & requirements that should be followed for the road construction during laying of Base course.

2.PURPOSE

To execute the job in hand as per specified specification & required standards.

3.SPECIFICATIONS FOLLOWED

Standard specification for road & bridge construction by Punjab Highway Department.

4.ASSHTO REFERENCE (S)

i.AASHO T–147 (Modified)
ii.AASH T–180 (Modified Proctor)

5.LIST OF EQUIPMENT

Grader
Road Roller
I.)Static Road Rollers
II.)Vibratory Road Rollers
Plate Compactor
Mechanically operated dumpers

6.METHODOLOGY

i.)Before laying the base material (water bound macadam) any ruts or soft yielding places/ material that appear on the sub-grade or sub-base will be rolled until firm.

ii.)Dumping of the base material shall ten be carried out to the prepared surface, spreading of this dumped material will then be by power grader. Course aggregate shall not be spread more than 15000 sq. ft. and not more than 500 linear ft. in advance of rolling.

iii.)The rolling will be commenced both on the shoulder and base-course in order to compact until the shoulder and aggregate are firmly bounded together.

iv.)After shoulder and base-course has been firmly rolled, then rolling will carry out from edges to center, the rolling will proceed in such a manner that half of rolling area will be over lapped in every rolling turn. The rolling will be continued until the surface is firmly, even and true to line, grade and crown.

v.)After compaction the course aggregate, sufficient clean, dry screening shall be uniformly applied, to fill all the voids. Dry rolling will be continued while screenings are being applied. For the cleaning, hand brommers will be used. Screening shall be spread in thin layers at a uniform and slow rate to ensure the void filling.

vi.)After the screening, the macadam shall be sprinkled with water, the sprinkler will be followed by the vibratory roller. The process/ rolling will be continued until compaction of entire depth has been achieved.

vii.)After the proper condition of compaction, is attained, the density test in accordance to AASHO T-180 (Modified Proctor) will be performed. All results are required to be a minimum 97% of maximum dry density.

viii.)The surface of the final layer of base-course will be at consistent designated level ± 3/8” in 10ft. from true profile and cross section.
