Asphalt Pavement Construction Asphalt InstituteAsphalt

Paving on a firm, stable, well-draining crushed aggregate base might be given more leeway than a thin asphalt overlay. Raining or not, new pavement must be placed on a firm, unyielding base. Critical ideas to keep in mind when dealing with rain: rain will cool the asphalt mix and could make obtaining proper compaction more difficult

Compaction is the elimination of excess air spaces (voids) in a soil by mechanical means. Vibration is a good mechanical means in sand soils; compression and impact are more successful means of compaction in clay soil. Some common types of equipment used for compaction on sand are track-type dozers, vibrating rollers, wobble-wheel rollers and
