(Date of Event Which Requires Filing of this Statement)

If the filing person has previously filed a statement on Schedule 13G to report the acquisition that is the subject of this Schedule 13D, and is filing this schedule because of §§240.13d-1(e), 240.13d-1(f) or 240.13d-1(g), check the following box. S

Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See Rule 13d-7 for other parties to whom copies are to be sent.

^* The remainder of this cover page shall be filled out for a reporting person's initial filing on this form with respect to the subject class of securities, and for any subsequent amendment containing information which would alter disclosures provided in a prior cover page.

The information required on the remainder of this cover page shall not be deemed to be "filed" for the purpose of Section 18 of the Securities Exchange Act of 1934 ("Act") or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

The following constitutes Amendment No. 1 (“Amendment No. 1”) to the statement on Schedule 13D previously filed by the undersigned on January 3, 2012 (the “Schedule 13D”).

Item 3 of the Schedule 13D is hereby amended and restated as follows:

The Common Shares and the Issuer's 9.5% Convertible Secured Notes ("Convertible Notes") covered by this statement were purchased in the ordinary course of business by the Accounts (as defined below) for an aggregate purchase price of $27,695,905. The source of funds for the purchases was assets of the Accounts available for investment.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) Based upon the Issuer's Quarterly Report on Form 10-Q, filed on November 14, 2011, there were 12,867,239 Common Shares outstanding as of November 11, 2011.

As of February 23, 2012, Whippoorwill may be deemed to be the beneficial owner of an aggregate of 3,779,714 Common Shares, representing 26.7% of the Common Shares. Of such beneficially owned Common Shares, 2,486,762 were held as Common Shares and 1,292,952 are issuable upon conversion of U.S. Concrete's 9.5% Convertible Secured Notes ("Convertible Notes"). The calculation of the number of Common Shares issuable upon conversion of the Convertible Notes is based on the conversion price on February 23, 2011 of $10.50 per share and $13,576,000 aggregate principal amount of Convertible Notes that may be deemed beneficially owned by Whippoorwill on such date.

The Common Shares and Convertible Notes disclosed herein as beneficially owned by Whippoorwill are held for the account of various funds and third party accounts (the "Accounts") for which Whippoorwill has discretionary authority and acts as general partner or investment manager.

Each of Mr. Greenhaus, as President and Principal of Whippoorwill, and Mr. Gendal, as Principal of Whippoorwill, may be deemed to beneficially own all the Common Shares and Convertible Notes beneficially owned by Whippoorwill.

(b) See Items 7 through 10 of the cover page for each Reporting Person.

(c) The transactions in the Issuer's securities by the Accounts during the 60 days prior to the filing of this Schedule 13D are listed in Exhibit A attached hereto and incorporated herein by reference. The transactions were effected through one or more brokers in the market.

(d) The Accounts have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Shares reported as beneficially owned by Whippoorwill. The following Accounts beneficially own more than 5% of the Common Shares: (1) WellPoint, Inc., an Indiana corporation, (2) Whippoorwill Distressed Opportunity Fund, L.P., a Delaware limited partnership; and (3) Whippoorwill Offshore Distressed Opportunity Fund, Ltd., a Cayman Islands exempted company limited by shares.

(e) Not applicable.

Item 6 of the Schedule 13D is hereby amended and restated as follows:

Note Purchase Agreement

The notes were issued pursuant to a Note Purchase Agreement, dated August 26, 2010 (the "Note Purchase Agreement"), between the Issuer and certain parties thereto. Pursuant to the Note Purchase Agreement, the Issuer has undertaken certain obligations with respect to the issuance and maintenance of the Notes. The full text of the Note Purchase Agreement is set forth in Exhibit B and incorporated herein by reference.

Registration Rights Agreement

Holders of the Convertible Notes reported as beneficially owned in this Schedule 13D have the benefit of a registration rights agreement, dated August 31, 2010 (the "Registration Rights Agreement"), under which the Issuer agreed, pursuant to the terms and conditions set forth therein, to register the Convertible Notes and the Common Shares into which the Convertible Notes convert. Under the Registration Rights Agreement, the Issuer was required to use commercially reasonable efforts to file shelf registration statements covering the resale of the Convertible Notes, the resale of Common Shares issuable upon conversion of the Convertible Notes and Common Shares issued to holders to pay interest, premium or other amounts owed to holders of the Convertible Notes. Such registration statements on Form S-1 were declared effective by the Securities and Exchange Commission on April 8, 2011 and October 26, 2011.

Under the Registration Rights Agreement, holders of the Convertible Noteholders are also entitled to unlimited piggyback rights on any registrations with respect to an underwritten offering of securities by the Company for its own account, subject to certain exceptions. The foregoing registration rights are subject to customary limitations and exceptions, including the Issuer's right to defer registration in certain circumstances and certain cutbacks by underwriters. The full text of the Registration Rights Agreement is set forth in Exhibit C and incorporated herein by reference.

Joint Filing Agreement

On February 27, 2012, the Reporting Persons entered into a Joint Filing Agreement (the "Joint Filing Agreement"). A copy of the Joint Filing Agreement is filed herewith as Exhibit D and incorporated herein by reference.
