FEATURE
— asphalt should be laid and compacted while it is within the optimal temperature range to ensure proper bonding and compaction . With hot joints you will want to keep your endgate up and level with your extension , and overlap two to three inches using the crank or tow points to adjust . If you also have grade control , many will set that up on one side as a joint matcher . Again , keep your eye on the clock as that shoulder or edge due to not being compacted will have voids . You will want to get this rolled quickly within your temperature window , which can lead to water infiltration and pavement failure .

Properly paving asphalt joints is a meticulous process that involves several critical steps : edge preparation , tack coating , joint formation , and mix temperature and compaction . By following these best practices and using the right techniques , the integrity and longevity of asphalt pavements can be significantly enhanced .
Each step , from ensuring clean , straight edges to achieving the correct compaction density , plays a vital role in preventing common issues such as water infiltration and premature pavement failure . Implementing these practices and following local department of transportation and bid specs will result in durable , high-quality asphalt pavements with well-constructed joints . By understanding the importance of joints and implementing these practices , paving professionals can deliver high-quality , long-lasting parking lots that require minimal maintenance .
