Maryland State Highway AdministrationAggregate BulletinMaryland State Highway AdministrationAggregate Bulletin1. IntroductionThis bulletin contains the qualified list of aggregate producers with the physical testdata. The bulletin will be updated on a quarterly basis. The last day of January, April, Julyand October of each year will be the publishing date. Published bulletin data will bevalid for one year. For instance, if a test is required to be performed each year, for testdata published in the 1st quarter, new test data will be due by the beginning of the 1stquarter of the next year. We encourage producers to keep track of their records,including due dates and submit their requests for aggregate testing on time. Producersare responsible for informing the Soils and Aggregate Technology Division (SATD) of anychanges to producer information, such as producer name, quarry name, subsidiaryproducer’s name, contact information, qualified use of aggregate.The data listed in the aggregate bulletin are considered to be representative of materialsupplied by a particular source of aggregate. The materials contained within thisdocument are not meant to represent all aggregate materials a particular quarry canproduce or supply. It is emphasized that the listed data must not be interpreted inabsolute terms. The information is provided as a guide for the expected quality of thematerial furnished by a listed source.2. Process for Listing as a Qualified Aggregate Source in MDSHAAggregate BulletinI.Written RequestThe aggregate producer shall submit a written request to:Dr. Intikhab Haider, Division ChiefSoils and Aggregate TechnologyMaryland State Highway Administration7450 Traffic DriveHanover, MD 21076IHaider2@mdot.maryland.govPage 1
Maryland State Highway AdministrationAggregate BulletinA. The SATD requires the producers to submit their written requests before thequarterly aggregate bulletin update. Please refer to the flow chart in Section II for“MDSHA Annual Quality Testing Process.” If samples are tested at MDSHA lab, weare requesting the producers to deliver aggregate samples to the MDSHA laboratory45 days prior to the next publishing date of the aggregate bulletin in order to publishthe test data on time.B. Please refer to Appendix A for “Aggregate Quality Test Request” Form. Producersshall complete and submit this form for each material (i.e. No. 57, Concrete Sand,Mortar Sand, etc.) for each quarry.C. Safety Data Sheet (SDS): All requests must be accompanied by a Safety Data Sheetwith specific quarry location with the effective date. No aggregate will be acceptedprior to receipt of the SDS.II.MDSHA Annual Quality Testing ProcessProducer submits request to MDSHA (Note 1)MDSHA responds to Producer within 10working days with required testsMDSHA LabProducer responds to MDSHA within 10working days with testing facility.

If aggregate samples are tested at the MDSHA laboratory, upon the receipt ofpayment or confirmation of valid contract charge number, the SATD will send anotice to the producer for sampling. Also, SATD will provide “Aggregate Test forQuality,” Form 12, Appendix B, to producers for logging each sample for eachquarry. The producers are required to complete this form and submit back to theMDSHA lab along with samples at the address mentioned above. The sampling shallbe in conformity with AASHTO R90Page 4Updated: August 02, 2021

Otherwise, the aggregatesource does not qualify for use as a high friction aggregate.(**)ASR determined in accordance with ASTM C 1293, Determination oflength change of concrete due to Alkali Silica Reaction.DFVDynamic Friction Value is defined as a coefficient of friction multiplied by100. Accordingly, coarse aggregate is categorized as three broadcategories: high, standard, and low DFVs, designated as HDFV, SDFV, andLDFV. These categories are presented below in detail:HDFV: Category I Category II Category III(HDFV I): DFV is equal to 50(HDFV II): DFV is equal to 45(HDFV III): DFV is equal to 40SDFV: Category IV Category V(SDFV IV): DFV is equal to 30(SDFV V): DFV is equal to 25LDFV: Category VI(LDFV VI): DFV is less than 25Page 12Updated: August 02, 2021

HASH ALGORITHMS MD5 - Default Algorithm of the Hash Function, Fast not as secure SHA - Secure Hash Algorithm FIPS SHA-1 160 bit Algorithm designed by the NSA SHA-2 (SHA-256 and SHA-512) also designed by the NSA SHA-3 winner will be announced by NIST in 2012 Algorithm support determined by JCE. ColdFusion Enterprise installs RSA BSafe Crypto-J Provider for FIPS-140 .
In basic terms, SHA is a component of digital certificates used to ensure that data has not been modified. SHA-2 is the technical successor to SHA-1 and provides greater security than SHA-1. As computing power increases, SHA-1 will be able to be decrypted more easily and susceptible to exploitation by criminals and hackers.
Master Utility Agreement MDOT SHA and The Company 3 . SECTION 2. MDOT SHA UTILITY PERMITS . A. After execution of this Agreement, the appropriate MDOT SHA District(s) will be notified that the Company is an Authorized Public Utility, and that the appropriate MDOT SHA District(s) may begin to issue the MDOT SHA Utility Permits to the Company.
A step-by-step migration guide to SHA-2 signed SSL certificates SHA-2 adoption: The challenges Switching to the secure SHA-2 hashing algorithm is easier said than done. But with Key Manager Plus, a web-based key management solution, it doesn't have to be. Key Manager Plus helps you consolidate, control, manage, monitor, and audit the entire

Section 2: Aggregate Data Dictionary The Aggregate Data Dictionary describes the aggregate data elements required to be entered for each chart-abstracted measure. It specifies those data elements that a hospital must aggregate after it processes its patient-level data through the measure algorithm. These aggregate data
SHA-256 Coprocessor with 1-Wire Master The SHA-256 coprocessor in Figure 1 is an I²C slave controlled by a host processor. From the host's I²C port the SHA-256 coprocessor appears as a 256-byte read/write memory with certain regions (data elements) assigned for special purposes. Security Logistics
The SHA-256 Secure Coprocessor The SHA-256 secure coprocessor in Figure 1 relieves the host processor from performing SHA-256 computations. More importantly, the secure coprocessor embeds protected memory that securely stores a master secret. Additional memory is set aside to store and protect other data elements used to compute
