Specifications include, but are not limited to: This work shall consist of a Type II or Type III Micro-Surfacing system, which shall be a mixture of mineral aggregate, cationic polymer modified asphalt emulsion, mineral filler, water, and other additives mixed and placed on the paved surface in accordance with these specifications and to the dimensions designated by the District Engineer or their designee. Type II micro surfacing aggregate gradation is used to fill surface voids, address surface distress, seal and provide a durable wearing surface. Type III aggregate gradation is used to provide a maximum skid resistance and improved wearing surface. Type III micro surfacing is appropriate for heavily traveled pavements or for rut filling. The micro-surfacing system shall produce a cured mixture with a homogeneous appearance, a firm surface adhesion, and a skid resistant texture.
