![]() Care should be taken to neatly construct the joint at a right angle to the centerline of the roadway. %PDF-1.7 Most paver manufacturers have developed hydraulically extendable screeds that trail the main screed on the paver. If it falls at the free edge of the pavement, the core location should be moved 2 inches in from the edge. The first is the frequency of vibration and the second is the amplitude of the compactive effort. ![]() These vibratory rollers can be operated in any one of three modes: static, with one drum vibrating and one drum static, and with both drums vibrating. When using drum mix plants, the aggregate moisture content of each stockpile should be taken at least once a day and the number entered into the plant control system. All personnel involved in the project must be required to comply with all safety standards applicable to the type of construction and asphalt paving work to be carried out. ![]() The screed of the second paver must be set at the same level as the screed of the first paver this will prevent the screed of the second paver from dragging on the mix placed by the first paver. Every year, MDOT produces an updated version of the state transportation map. The importance of staying within the surface tolerance for smoothness cannot be overemphasized. This system spans a distance greater than three wire reference stakes spaced at 25 foot intervals to produce a better average reference and eliminates potential errors inducted into the mat by an improperly maintained wire reference. A fast means of communication should be established between the plant and the paving crew so that any changes to the mixture can be promptly communicated.

If the millings have aggregates larger than what is required for the mix design, it should be processed (crushed and/or screened) prior to stockpiling*. Once the Contractor has finished the rolling operation, the inspector will identify the locations where the density cores will be taken these locations are randomly selected both longitudinally and transversely. This floating screed principle is employed on all modern pavers in use today. The trucks should not be loaded by slowly driving forward while the mix is being delivered from the silo.
