Dept. of Transportation. Transportation Research DivisionUS Transportation CollectionIn previous years there has been a problem with longitudinal jointdeterioration, due in part to poor construction techniques.The degradation of the longitudinal joints has increased the cost ofmaintaining these projects and caused unnecessary reflective cracking whenoverlaid.To reduce the effects of this type of cracking the Maine Department ofTransportation (MDOT) is proposing the use of an experimental product as well asvarious hot mix asphalt (HMA) rolling techniques to increase longitudinal jointdensitie
