CY2019	us-gaap	Use Of Estimates UseOfEstimates	<span style="font-family:inherit;font-size:10pt;font-weight:bold;">Use of Estimates</span>—Preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, valuation of deferred tax assets, goodwill, intangibles and other long-lived assets, the tax receivable agreement (“TRA”) liability, pension and other postretirement obligations, and asset retirement obligations. Estimates also include revenue earned on contracts and costs to complete contracts. Most of the Company’s paving and related services are performed under fixed unit-price contracts with state and local governmental entities. Management regularly evaluates its estimates and assumptions based on historical experience and other factors, including the current economic environment. As future events and their effects cannot be determined with precision, actual results can differ significantly from estimates made. Changes in estimates, including those resulting from continuing changes in the economic environment, are reflected in the Company’s consolidated financial statements when the change in estimate occurs.
CY2019	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	<span style="font-family:inherit;font-size:10pt;font-weight:bold;">Business and Credit Concentrations—</span><span style="font-family:inherit;font-size:10pt;">The Company’s operations are conducted primarily across </span><span style="font-family:inherit;font-size:10pt;"><span>23</span></span> U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Utah, Kansas and Missouri. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers and management does not believe that a significant concentration of credit exists with respect to any individual customer or group of customers.
