This Work also includes the replacement of existing elastomeric concrete nosing as shown and specified.

00584.80 Measurement - Replace this subsection, except for the subsection number and title, with the following:

The quantities of Work performed under this Section will be measured according to the following:

(a) Elastomeric Concrete Nosing Material - Elastomeric concrete nosing Material will be measured on the volume basis for Material placed in the nosing. When using a mobile mixer, the quantities will be determined by converting the weight identified on the mixer’s automatic metering device to volume, using the manufacturer’s published unit weight and yield factor. When hand batching, the quantities will be determined based on volumes calculated by batch weights and published unit weights of the Material. If placed monolithically with a premixed polymer concrete overlay, the volume will be calculated by multiplying the average depth of the nosing by the measured area.

(b) Constructing Elastomeric Concrete Nosing - Constructing elastomeric concrete nosing will be measured on the area basis. The length will be determined by measuring from face of curb to face of curb along the centerline of the joint. The width will be determined by measuring to the outer limits of the installed Material perpendicular to the joint. Subtract the area of the joint opening from the area calculation.

Joint seal Material will be measured according to 00585.80.
