the pavement damage from the axle loads of the various vehicles expected to use the pavement over its designed life, usually 20 years. As a general principle, the heavier and more numerous the vehicles using the road, the thicker the pavement needed to support them. For example, The Asphalt Institute recommends various asphalt
Construction started on October 11, 2018 and lasted for four weeks due to the weather condition. The existing pavement was a 40 years old PCC pavement with numerous cracks at the joints and midspan. The pavement had also been rehabilitated at several spots because of intensive damages.
• Proper design and construction are absolutely necessary if the pavement is to perform. • Must be uniform throughout pavement's life. • Poor subgrade/subbase preparation can not be overcome with thickness. • Any concrete pavement, built of any thickness, will have problems on a poorly designed and constructed subgrade or subbase.

Road construction is the process of keeping a road in a state of good repair. The task consists of paving, reclaiming and/or rehabilitating the degraded pavement so it can be brought to a more optimized and safe condition. Road construction can entail repairing a portion of the road or completely demolishing and rebuilding the entire road.
At Peek Pavement Marking, we combine one of the largest vehicle fleets in the industry with highly trained crews and a commitment to service second to none. No job is too large or small. Whether you need to mark half a mile of new asphalt or hundreds of miles of interstate highway, we are equipped and staffed to get the job done right and on time.
Pavement construction plays a role in the ride quality and fuel efficiency of the vehicle during the pavement's operation, which relates to traffic, paving material properties, how well the road is maintained, and other factors. In addition, fuel efficiency can be increased through improved pavement design, construction and maintenance.
Roadway Pavement Markings . for traffic control devices. Amateurish, homemade or damaged pavement markings are more likely to be disregarded. 4 - Have one simple message .

3.) Asphalt Paver. Also known as asphalt finisher, paver finisher, or paving machinery, asphalt paver is a roads equipment used to lay asphalt on the surface of a road, parking lot, bridge, or other such facilities and to do some minor compaction before a roller takes over. The asphalt is added from a dump truck into the paver's hopper.
