摘要： Discloses apparatus and methods for providing a longitudinal joint between a cold (previously laid) and a hot (freshly laid) mat of paving material, such as asphalt, and wherein after the rolling of the paving material the joint region between the cold and the hot mats is of a high and substantially uniform density. To this end, there is provided a quantity of additional fresh (hot) paving material formed into a shaped charge and disposed adjacent the edge of the cold mat section. The quantity of additional fresh paving material contained in the shaped charge and the configuration of the shaped charge are made such that after appropriate rolling of the paving material, the lateral and transverse compaction forces generated force sufficient fresh paving material into the joint region between the cold and hot mat sections to bring the density of the paving material in such joint region to substantially the specified density and substantially the same as that of the cold and hot mat sections. That is, the final resulting density of the entire paved area comprising the two mat sections and the longitudinal join therebetween is substantially uniform.
摘要翻译：公开了用于在冷（预先铺设的）和热（新鲜铺设的）铺路材料垫（例如沥青）之间提供纵向接头的装置和方法，并且其中在铺路材料滚动之后，冷和热之间的接合区域垫子具有高且基本均匀的密度。为此，提供了一定量的新鲜（热）铺路材料，其形成为成形装料并且邻近冷垫部分的边缘设置。成形装料中包含的额外的新鲜铺路材料的数量和成形装料的构造被制成使得在铺路材料的适当轧制之后，横向和横向压实力产生的力将足够的新鲜铺路材料施加到冷的和热垫部分，以使该接合区域中的铺路材料的密度基本上与冷和热垫部分的密度基本相同。也就是说，包括两个垫部分的整个铺砌区域的最终产生的密度和它们之间的纵向连接基本上是均匀的。

摘要： A screed assembly for an asphalt paving machine includes a lower screed plate, an upper screed plate and a heating element that is in contact with the lower screed plate. The screed assembly also includes a compression bolt assembly having a primary bolt, a compression bolt and a compression spring. The primary bolt has a through hole, and the compression bolt is adapted to be inserted through the hole of the primary bolt. The compression spring is adapted to be placed over the lower end of the primary bolt, so that the compression bolt assembly may cooperate with the upper screed plate to apply a compression force to the heating element on the lower screed plate.
