Roadway pavement join insert forms tee-section rail of material mix not sticking at normal temperature and addressed to parts both sides of join to round off one side and verticalize on other side.
Roadway pavement join insert forms tee-section rail of material mix not sticking at normal temperature and addressed to parts both sides of join to round off one side and verticalize on other side.
The rail insert (7) comes in tee section and made of material which does not stick at normal temperature and when a new road pavement part (4) is addressed to a part (2) already laid, the tee section of the rail (7) facing the new part (4) in the throat area rounds off between the center web (8) and the horizontal crosspiece (9) of the tee. Where the rail faces the part (2) already laid, the throat affords a rightangle between. The insert is installed in the newly cast parts which are thus still soft and is forced far enough into the join to ensure the rail tee (9) abuts the surface (23) of at least one of the two pavement parts (2 or 4).
