【 摘 要 】

Waste material affects the road construction project consisting of ready mix concrete, lean concrete, B aggregate, landfill and cement. Identify risks by looking at the source and causes of waste material in the five materials. The source and causes of waste material for road construction do not yet exist. So it is necessary to take literature from a simplified building project so that it can be used for road construction projects with the help of experts. Risk identification is carried out with primary data, namely the questionnaire, then consulted by experts with the Delphi Method with three stages. The results of the Delphi method produce each of the causes of waste material for road construction projects that result in the identification of Early Risks. Ready Mix concrete has 8 sources of waste material and 21 causes of waste material. Concrete Concrete has 7 sources of waste material and 18 causes of waste material. Aggregate B has 7 sources of waste material and 15 causes of waste material. Landfill has 8 sources of waste material and 26 causes of waste material. Cement has 7 sources of waste material and 31 causes of waste material.
