119.3.1 Spreading

The material (subbase) shall be delivered to the roadbed as a uniform mixture.Segregation shall be avoided during spreading and the final compacted layer shall befree from concentrations of coarse or fine materlals. Before spreading the sub basematerial, the exposed surface after the removal of water bound base I subbase shallbe scarified watered and compacted to the required density and the payment for suchcompaction shall not be made separately and is included under this section.

The material shall be deposited on the roadbed in a quantity which will provide therequired compacted thickness without resorting to spotting, picking up or otherwiseshifting the sub base material.

Where the required thickness is 15 cm or less, the aggregates may be spread andcompacted in one layer. Where the required thickness is more than 15 cm, theaggregates shall be spread and compacted in 2 (two) or more layers of approximatelyequal thickness, and the maximum compacted thickness of any one layer shall notexc,eed 15 cm. All subsequent layers shall be spread and compacted in a similarmanner.

CompactingThe moisture content of sub base material shall be adjusted prior to oompaction bywatering with approved sprinklers mounted on trucks or by drying out, as required, inorder to obtain the required compaction.

The sub base material shall be compacted by means of approved vibrating rollers orsteel wheel rollers (rubber tire rollers may be used as a supplement), progressinggradually from the outside towards the centre, except on superelevated curves, wherethe rolling shall begin at the low side and progress to the high side. Each succeedingpass shall overlap the previous pass by at least one third of the roller width. While therolling progresses, the entire surface of each layer shall be properly shaped anddressed wlth a motor grader, to attain a smooth surface conforming to the requiredlines and grades.

Following the initial rolling, dry screenings shall be applied uniformly over the surface.Dry rolling shall be continued while screenings are being applied. The surface shall beswept with mechanical or hand brooms to aid spreading of the screenings.

When the interstices in the coarse aggregate are fillwith screenings, the surface shallbe sprinkled with water until it is saturated. The rolling, sprinkling and application ofadditional screenings shall continue until a grout is formed that fills all the voids andforms a wave of grout in front of the roller.

Any areas inaccessible to rolling equipment shall be compacted by means ofmechanical tampers,

The compaction of the sub base layer shall be continued untilthe result is satisfactoryto the Engineer.

lf the layer of sub base material, or part thereof does not conform to the required finish,the Conkactor shall, at his own expense, rework, water, and recompact the materialbefore the nexl layer of the pavement structure is oonstruoted.

lmmediately prior to the placing of the first layer of base oourse, the sub base layer(both under the travelled way and the shoulders) shall be to the required level andshape. Any watering and reshaping of the surface of the sub base will be at theContractor's expense.No material for construction of the base shall be laid until theapproved by the Engineer. ,7'.-,,,,'.,n
