KC District Aggregate Specifications.pdf

This document is a specification sheet for the Kansas City District outlining aggregate material requirements for various road construction and maintenance applications. The specifications detail eight distinct material types required for surfacing, seal coats, snow and ice control, base aggregate, and cinders. Specification 3 addresses Grade A or B aggregate for surfacing under Section 1006, with the explicit note that Type 1 aggregate for base will not be accepted. Specification 4 covers Grade C crushed stone for seal coats and haydite for scrub seals under Section 1003. Specifications 5 and 6 address snow and ice control materials, including limestone chips meeting specific gradation requirements with percentages passing through various sieves and limestone-based fine aggregate. Specification 7 requires cinders composed of coal slag with 100 percent passing through a 3/8-inch sieve, subject to District Engineer approval. Specification 8 designates Type 1 aggregate for base materials under Section 1007.

The document establishes material gradation standards and sieve size requirements for each specification to ensure consistent quality across projects. Material sources and types are subject to approval by the Kansas City District Engineer or an authorized representative. The specifications reference existing sections within the district's broader standards (Sections 1002, 1003, 1005, 1006, and 1007) that contain additional technical requirements for fine and coarse aggregates. No pricing information, contract terms, quantities, delivery schedules, or bidding procedures are included in this specification document, which serves as a technical reference for material procurement and quality assurance.
