MDT specification for hydrocarbon thermoplastic hot extruded in to grooves cut into the asphalt, or inlaid. This is also in line with what the City of Bozeman specifies for inlaid thermoplastic. Please confirm that Type H markings are to be inlaid hot extruded hydrocarbon thermoplastic. Please let us know if this can be an alternative to Thermoplastic

Pavement Marking spec.

The gravity retaining walls depicted in Sheets J1 through J8, and specified in Section 254, are impractical in precast block products. Precast block products for gravity walls are rectangular products, however the wall elevations show vertically curved grades along the bottom of cut walls and top of fill walls that are noted as not allowing steps. This could only be constructed, without unsightly gaps at the face of the wall, if the sides of multiple blocks were cut and fit on site (which would be prohibitively expensive).

In addition, several of the walls are shown to be set on a vertical grade without endcaps to prevent lengthwise sliding (especially in this seismic loading condition).

Can the noted bottom of cut walls and top of fill walls be minimally stepped as required to meet general grading and, as required, set the base of wall on a buildable longitudinal slope?

Please Bid according to the plans and specs 1/2/2018
