A. QUESTIONS AND ANSWERS

1. Question: We have a question about spec P-211. It calls for an LBR of 125. From our experience lime

rock does not achieve that high of an LBR. Would crushed concrete or GAB be a suitable substitute?

Answer: The use of P-209 Crushed Aggregate Base Course may be used in lieu of P-211 Lime Rock

Base Course at the Contractor’s discretion at no additional cost. Payment for the use of P-209 in lieu of

P-211 will be made in accordance with the P-211 item. Refer to the attached Specification P-209

Crushed Aggregate Base Course.

2. Question: Is the referenced project still scheduled to bid March 10 at 1:00 PM? Also, I would like to

know how bidders are being notified of addendums.

Answer: The Bid Opening remains Tuesday, March 10, 2026 at 1:00 PM CT as indicated in Addendum

No. 2. All addenda are issued through the City of DeFuniak Springs Requests for Bids, Qualifications

and Proposals website here: https://www.defuniaksprings.net/1230/Bids-RFPs. Addendum No. 4 is the

final addendum for this project.

ITEM P-209 CRUSHED AGGREGATE BASE COURSE

DESCRIPTION

209-1.1 This item consists of a base course composed of crushed aggregate base constructed on a

prepared course in accordance with these specifications and in conformity to the dimensions and typical

cross-sections shown on the plans. This item may be used in lieu of P-211 Lime Rock Base Course at the

Contractor’s discretion.

MATERIALS

209-2.1 Crushed aggregate base. Crushed aggregate shall consist of clean, sound, durable particles of

crushed stone, crushed gravel, and shall be free from coatings of clay, silt, organic material, clay lumps or

balls or other deleterious materials or coatings. The method used to produce the crushed gravel shall result

in the fractured particles in the finished product as consistent and uniform as practicable. Fine aggregate

portion, defined as the portion passing the No. 4 (4.75 mm) sieve shall consist of fines from the coarse

aggregate crushing operation. The fine aggregate shall be produced by crushing stone, gravel that meet

the coarse aggregate requirements for wear and soundness. Aggregate base material requirements are

listed in the following table.

1 The area of each face shall be equal to at least 75% of the smallest mid-sectional area of the piece.

When two fractured faces are contiguous, the angle between the planes of fractures shall be at least

30 degrees to count as two fractured faces.

2 A flat particle is one having a ratio of width to thickness greater than five (5); an elongated particle is

one having a ratio of length to width greater than five (5).

209-2.2 Gradation requirements. The gradation of the aggregate base material shall meet the

requirements of the gradation given in the following table when tested per ASTM C117 and ASTM C136.

The gradation shall be well graded from coarse to fine and shall not vary from the lower limit on one sieve

to the high limit on an adjacent sieve or vice versa.
