Asphalt concrete shall conform to Section 39 of the State Specifications, and these

Asphalt concrete is designated as Type A, Type B, Type C, or Open Graded. Type C

asphalt concrete shall be as specified in the Special Provisions. Asphalt concrete is also

designated by gradation, according to percentage of crushed particles and sand equivalent of

the aggregate (for dense graded mixtures) or according to intended use (for open graded mixes)

and by class, according to texture of the mixture.

The Contractor's operations shall be conducted in a manner that will not harm or damage

existing facilities or improvements.

At locations where public traffic is routed over the base grade, the Contractor shall plan the

paving operations to minimize the delay of traffic.

The Contractor, when required to provide for the passage of public traffic through the work,

shall do so in accordance with the provisions of Section 12, "Construction Area Traffic Control",

of these Specifications.

23-2 MIX FORMULA AND DESIGN

The Contractor shall submit to the Agency for approval a job mix formula and mix design.

Mix designs shall be accompanied by current test results that indicate compliance with these

Specifications and the Special Provisions. A job mix formula shall be submitted by the

Contractor for each designation of asphalt concrete, based on samples of conforming aggregate

materials supplied for each source or supplier proposed by the Contractor, with optimum binder

content determined per California Test Method 367. The job mix formula shall establish a single

percentage of aggregate passing each required sieve size, a percentage of asphalt binder to be

added to the aggregate. The Agency will determine the binder content based on submitted mix

design. Binder content will be determined in accordance with California Test Method 382,

“Determination of Asphalt Content of Bituminous Mixtures by the Ignition Oven” or California

Test Method 379, “Method of Determining Asphalt Content by the Use of Nuclear Gauge”.

Where more than one source or supplier is designated to supply asphalt concrete, those

mixes will be kept separated. The mixes shall not be intermixed in the same lift or section of

pavement. The Contractor shall submit paving plans showing, in advance, where the mixes

from each source will be used. This paving plan will be subject to approval by the Agency.

For asphalt concrete that is to be placed on residential and collector streets (“minor

streets”), those streets with a right-of-way of fifty-six feet (56’) and less, aggregate for asphalt

concrete structural sections of one and one-half inches (1-1/2”) or greater in thickness shall be

Type A and shall meet the specifications for either one-half inch (1/2”) maximum, medium

grading or three quarter inch (3/4”) maximum, medium grading as specified in Section 39,

“Asphalt Concrete” of the State Specifications. For all other streets (“major streets”), unless

otherwise shown or specified in the Contract, aggregate for asphalt concrete structural sections

of one and one half inches in thickness shall be Type A and shall meet the specifications for

one-half inch (1/2”) maximum, medium grading; and aggregate for all asphalt concrete structural

sections of two inches (2”) or greater in thickness shall bee Type A and meet the specifications
