A Contribution to the Study of Joints on Concrete Pavements

vlaterials used as joint sealants on concrete pavements are zenerally classified in: - Preformed sealants. - Field molded sealants. l'his work shows the demanded characteristics for preformed .ealants and field molded sealants. The last ones are divided in :wo types: thermosetting -two component systems- coldap-rlied, and thermoplastics --one component- bot applied.:"or the selection of the above mentioned characteristics, aNarking plan was carried out with materials from the Spanishnarket; the results obtained have been used as conditionsiernanded for a good performance of sealant materials on con-rrete pavements.
