Book excerpt: When placing hot-mix asphalt concrete (HMAC), paving the full width of the pavement in a single pass is usually impossible; therefore, most bituminous pavements contain longitudinal construction joints. These construction joints can often be inferior to the rest of the pavement and can eventually cause an otherwise sound pavement to deteriorate more quickly. The objectives of this project were to (1) assess the density along the longitudinal construction joint of several Texas pavements to determine if a problem exists; (2) document information from the literature; (3) synthesize aviation construction data where a history of a joint density specification exists to determine if such a requirement can be met by paving contractors; and (4) modify current HMAC specifications to require joint density measurements if justification is verified.
