It is everyone’s desire to have successful chip seal projects. In the county of San Diego, private contractors compete to win this agency’s annual multi-million dollar chip seal contract because the contractors know that winning the contract will guarantee work for the majority of the chip seal season. But it isn’t that easy. An experienced contractor also knows the work involved in planning, scheduling and placing chip seals on a variety of roads, everyday, for several months. The county of San Diego wants the chip seal work done in one chip seal season. So the county of San Diego developed and incorporated a quality control and quality assurance (QC/QA) program into its contract specifications to insure quality materials are used on the project; this also helps prevent construction delays and reduce the number of damaged windshields. The county also recognizes the importance of when to advertise a chip seal project for bidding. They found that advertising in late winter or early spring allows bids to come in at a lower cost, and contractors have the maximum amount of warm weather available to do the work. This paper discusses the cooperative effort between the county of San Diego and private contractors to develop a QC/QA program for the county’s chip seal contracts. This paper covers topics such as road selection, when to advertise a project, material sampling and testing, equipment usage and maintenance, visual inspection of materials, and proper sequence of construction operations.
