One embodiment of the invention relates to a flexible sled that conforms to the contour of the pavement for applying a liquid emulsion onto a pavement surface comprising a rigid frame with flexible squeegee assembly adapted to be towed along a pavement surface. Another embodiment of the invention includes a hopper assembly for distributing aggregate Another embodiment of the invention Includes a sled for repairing ruts in wheel lanes of a road Another aspect of the invention is a polymer emulsion composition having a high coefficient of friction comprising a mixture of polymer resin blended with a mixture of cement and angular sand aggregate and titanium dioxide to provide a solar reflectance index number that ranges from 30 to 38 and a friction number in the range of 45 to 55.

Un mode de réalisation de l'invention concerne un traîneau flexible épousant le contour de la chaussée pour appliquer une émulsion liquide à la surface d'une chaussée comprenant un cadre rigide avec un ensemble racleur flexible permettant un halage le long de la surface de la chaussée. Un autre mode de réalisation de l'invention concerne un ensemble trémie permettant de répartir un agrégat. Un autre mode de réalisation de l'invention concerne un traîneau pour réparer les traces de roue sur les différentes voies d'une chaussée. Un autre aspect de l'invention a trait à une composition d'émulsion polymère au coefficient de friction élevé et comprenant un mélange de résine polymère combiné à un mélange de ciment, d'un agrégat de sable anguleux et de dioxyde de titane pour fournir un indice de réflectance solaire allant de 0,30 à 0,38 et un indice de friction allant de 45 à 55.
